Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of down-hole oil production tubing string is the two envelope of an a kind of band gaslift completion integrated pipe column.
Background technology
At present, the potentiality oil reservoir of some oil well is in the bottom of Water Flooding Layer, and Water Flooding Layer is referred to as high Water Flooding Layer.The flow string that in such oil well, is lowered to should have the function of the high Water Flooding Layer of shutoff, and can exploit bottom potentiality oil reservoir.Consult Fig. 1.The gaslift completion tubular column that is lowered at this oil well generally all is to adopt two envelope gas lift strings of giving up.The high Water Flooding Layer of shutoff mainly realizes that by lower packet 2, intubate 12, upper packer 3 two packers adopt and set the same packer of principle.Completion tubular column is made up of oil pipe 4 and gaslift seating nipple 11.Consult Fig. 2.Tubing string is lowered to process; Following pair of tube sealing post of elder generation; Promptly being lowered to upper packer 3, lower packet 2, two packers connects high Water Flooding Layer 8, two packers of shutoff through intubate 12 and sets simultaneously; Sleeve pipe 1 and the annular space that sets tubing string are suppressed checking upper packer 3 whether set, trip out the tubing string of giving up after setting.Be lowered to completion tubular column completion again with some gaslift seating nipples 11.
The subject matter that this completion tubular column exists is: (1) two envelopes and gaslift completion tubular column are through tubing string operation completion twice down, and the activity duration is long, has increased operating cost.(2) since two envelope to set principle the same, set simultaneously, lower packet can't verify whether set, thereby can not guarantee the effect of the high Water Flooding Layer of shutoff.(3) if will let the potentiality oil reservoir combination producing of high Water Flooding Layer and bottom later on, operation again, is salvaged two envelopes at lift pipe string, descend the completion gas lift string again, needs operation again, the increase operating cost.
The utility model content
The purpose of the utility model is: the two envelope of a kind of band gaslift completion integrated pipe column is provided, can tests two packers and seal the promoting the circulation of qi act oil recovery of going forward side by side.Reach and both can improve the high Water Flooding Layer effect of shutoff, create a kind of convenience for later high Water Flooding Layer utilization again, reduce flow chart, shorten the activity duration, finally reduce operating cost.
The technical scheme that the utility model adopts is: the two envelope of band gaslift completion integrated pipe column, mainly form by tubing shoe, ball seat, mechanical-set lower packet, the dark short circuit in school, the gaslift seating nipple of adorning blind valve, the upper packer of hydraulic setting, telescoping tube.It is characterized in that: annexation is from bottom to top: the top at tubing shoe connects ball seat, and ball seat top connects the upper packer of mechanical-set lower packet and hydraulic setting; Between the upper packer of hydraulic setting and mechanical-set lower packet, be connected with 35～60 oil pipes; On these 35～60 oil pipes, be connected with the dark short circuit in school, and the top of dark short circuit is connected with a gaslift seating nipple that blind valve is housed through oil pipe in the school; Top at the upper packer of hydraulic setting is connected with telescoping tube; The top of telescoping tube is connected with oil pipe; The top of oil pipe connects 3～15 gaslift seating nipples that blind valve is housed, and is connected with oil pipe in the upper end of the gaslift seating nipple that blind valve is housed on top, and oil pipe is connected to well head always.
What described mechanical-set lower packet adopted is the RTTS packer that positive tube post, pressurization set, and guarantees the effect that sets of mechanical-set lower packet;
What the upper packer of described hydraulic setting adopted is that the MCHR packer that sets is suppressed in classification.
The beneficial effect of the utility model: the two envelope of the utility model band gaslift completion integrated pipe column, can test two packers and seal the promoting the circulation of qi act oil recovery of going forward side by side.If will produce high Water Flooding Layer later on,, take out the tubing string operation and needn't go up working rig through pulling the blind valve in the gaslift seating nipple out.Reach and both can improve the high Water Flooding Layer effect of shutoff, create a kind of convenience for later high Water Flooding Layer utilization again, reduce flow chart, shorten the activity duration, finally reduce operating cost.
